Your logo is machined in reverse into a brass or magnesium die. It's a one-time cost, and reorders reuse the same die, usually at a reduced setup charge.
The heated die presses into the cover with serious force, permanently compressing the material into a crisp impression.
Pressed bare, it's a blind deboss: quiet, tone-on-tone texture. Pressed through a foil film, the impression fills with metallic color.
We check impression depth and edge crispness: deep enough to read at arm's length, never punching through the cover.
Pick a finish, then press the die into the journal.
Reorders reuse your die, so setup is usually reduced the second time. When in doubt: blind deboss on leather, foil on paper covers.
